Angular 2 Interview question and answer  What is the difference between  @Component  and  @Directive  in Angular? Components To register a component we use @Component meta-data annotation. Component is a directive which uses shadow DOM to create encapsulated visual behavior called components. Components are typically used to create UI widgets. Component is used to break up the application into smaller components. Only one component can be present per DOM element. @View decorator or templateurl template are mandatory in the component. Directive To register directives we use @Directive meta-data annotation. Directive is used to add behavior to an existing DOM element. Directive is use to design re-usable components. Many directives can be used per DOM element. Directive doesn't use View. Sources: http://www.codeandyou.com/2016/01/difference-between-component-and-directive-in-Angular2.html

Difference between a method and a function A  function  is a piece of code that is called by name. It can be passed data to operate on (i.e. the parameters) and can optionally return data (the return value). All data that is passed to a function is explicitly passed. A  method  is a piece of code that is called by a name that is associated with an object. In most respects it is identical to a function except for two key differences: A method is implicitly passed the object on which it was called. A method is able to operate on data that is contained within the class (remembering that an object is an instance of a class - the class is the definition, the object is an instance of that data).

Twitter bootstrap white gap on right side of page. This might be a little late but I found the other answers to be misleading. It is true that the row class is what is causing the issue, but that is because it is always supposed to be placed inside a container element. from  http://getbootstrap.com/css/  : Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding. The container element usually has a -15px padding on both right and left and the row class has a 15px padding on right and left. The two cancel each other out. If one of the two is not present you will see extra space.

Differences Between SVG and Canvas SVG is a language for describing 2D graphics in XML. Canvas draws 2D graphics, on the fly (with a JavaScript). SVG is XML based, which means that every element is available within the SVG DOM. You can attach JavaScript event handlers for an element. In SVG, each drawn shape is remembered as an object. If attributes of an SVG object are changed, the browser can automatically re-render the shape. Canvas is rendered pixel by pixel. In canvas, once the graphic is drawn, it is forgotten by the browser. If its position should be changed, the entire scene needs to be redrawn, including any objects that might have been covered by the graphic. Comparison of Canvas and SVG The table below shows some important differences between Canvas and SVG: Canvas SVG Resolution dependent No support for event handlers Poor text rendering capabilities You can save the resulting image as .pn...
